§  25.172   Requirements for reporting space station control arrangements.

   (a) The operator of any space station licensed by the Commission or
   granted U.S. market access must file the following information with the
   Commission prior to commencing operation with the space station, or, in
   the case of a non-U.S.-licensed space station, prior to commencing
   operation with U.S. earth stations.

   (1) The information required by § 25.170(b).

   (2) The call signs of any telemetry, tracking, and command earth
   station(s) communicating with the space station from any site in the
   United States.

   (3) The location, by city and country, of any telemetry, tracking, and
   command earth station that communicates with the space station from any
   point outside the United States.

   (4) Alternatively, instead of listing the call signs and/or locations
   of earth stations currently used for telemetry, tracking, and command,
   the space station operator may provide 24/7 contact information for a
   satellite control center and a list of the call signs of any U.S. earth
   stations, and the locations of any non-U.S. earth stations, that are
   used or may be used for telemetry, tracking, and command communication
   with the space station(s) in question.

   (b) The information required by paragraph (a) of this section must be
   filed electronically in the Commission's International Bureau Filing
   System (IBFS), in the "Other Filings" tab of the space station's
   current authorization file. If call sign or location information
   provided pursuant to paragraph (a) of this section becomes invalid due
   to a change of circumstances, the space station operator must file
   updated information in the same manner within 30 days, except with
   respect to changes less than 30 days in duration, for which no update
   is necessary.
